' UNITED sTATEs PATENT oEEroE. `JOHN C. HILL, ILLINOIS. SIGHT-FEED.

Specification of Letters Patent. Patented May 14, 1907.

Application led July 16,1906. Serial No. 326,327.

portion of said 3, the commu-nication of the port with the outletpassage 4 is closed, and the upper port 7 is brought above the inclosingwall of the passage 2 so that the lubricant will discharge outwardlythrough said port 7 against a transparent wall of the appliancehereinafter described, to give a visible indication of the flow.

8 is a conical valve at the upper end of the piston valve 5, and adaptedin the firstdescribed position of the valve above described, to seatupon and close the upper end of the passage 2, to prevent leakagetherefrom of the lubricant.

9 is a spring the tendency of which is to hold the piston valve to itsfirst described position, and to this end the said valve will beprovided with a guiding and operating To all whom it may concern: lpoint of use. In the other Be it known that I, JOHN C. HILL, a citivalve5, illustrated in Fig.

zen of' the United States of America, and a resident of Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements. in Sight- Feeds, of which the following is aspecification.

This invention relates to means for visibly 1o indicating the flow ofthe fluid in its passage simple and durable arrangement and combinationof parts whereby a temporary visible iow of the fluid can be had at thewill of the of the deliveries of a multiple delivery pump, all as willhereinafter more In the accompanyinv' l is a front elevation of amultiple delivery indicator constructed in accordance with the presentinvention. Fig. 2 is a transverse sec` tion on line x` Fig. 1. Fig. 3 isa detail transverse section illustrating the parts in a reverse position,to that shown in Fig. 2. Fig. 4 is a detail transverse section on linex-x Fig. 1. Fig. 5 is a detail plan view of the plate 3o which locks thehandles from rotation.

.Similar numerals of reference indicate like parts in the severalviews.'

eferring to the drawings, 1 is a main trunk or housing, which in'themultiple and 3 5 preferred form of the appliance lis formed with aseries of vertical passages 2, which at their upper ends are formed withseats for the controlling valves hereinafter described.

3 are a series of inlet passages connecting 4o with the lower end of theseries of passages 2. and adapted to conduct the multiple discharges ofa pump into passages 2, aforesaid. 4 are a series of outlet passagesconnecting with the series of passages 2, near ends thereof, and areadapted for connection with a series of pipes extending to the points tobe lubricated.

5 are a series of tubular piston valves sliding in the upper portions ofthe vertical pas- 5o sages 2, and veach provided with a pair of lateralports 6 and 7, arranged in vertical separated relation as shown, andadapted in one position of the -valve 5, illustrated in Fig. 2, toregister the passage 2, through the lower port 6, with the outletpassage 4, so that the iiow of the lubricant will be to the drawingsz`Figure ving into the top of the housing l as shown.

12 is anoperating handle,

the top of the bushing downward swing of the operating handle to liftthe piston valve into the position in which it gives a visibleindication of the flow of the lubricant.

14 is a late secured to the top of the housing 1, andp provided with aseries of rectangular recesses 15 corresponding with the number ofoperating handles 12, and adapted to form receiving cavities for thelower ends of said handles to prevent any rotation of said handles fromtheir proper position in relation to the main housing.

16 is a vertical plate arranged in front of the series of'guide stems,springs, etc., above described, and adapted to from view, and at thesame time constitute a reflector to aid in a better observation of thefiowof the lubricant heretofore described.

I7 are a series of orifices in the plate 16 for the outward discharge ofthe lubricant against the transparent wall of the ap liance.

18 is the transparent wall of the appliance secured to the front thereofin any usual and suitable manner. Such wall 18 is arranged a shortdistance in front of the vertical plate 16, before described, so as toleave a collecting chamber for the lubricant in making a visible test ofthe flow thereo conceal the same IOO IIO

19 is an outlet passage connecting with the loiver end of saidcollecting chamber, and adapted for connection With a drain pipeextending to the supply tank of the pump.

Having thus Jfully described my said invention, What l claim as neWlanddesire to secure by Letters Patent, is 1 l A visible indicatingappliance for lubri cators and the like, comprising a housing formedwith a main passage, inlet and outlet passages communicating with saidmain passage at different points in its length, a piston valve moving insaid passage and provided with lateral ports adapted to control thedirection of the flow of luid Vfrom the main passage, means 'forimparting a sliding movement to said piston valve, and a transparentWall connected to the housing and forming a part olf' the inclosing Wallolf' a collecting chamber lormed in said housing.
